ADJUSTABLE PANEL-BOARD SUPPORT.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Application filed December 13, 1910. Serial No. 597,139.

To all whom it may concern:

Be it known that I, WILLIAM WURDACK,

-a citizen of the United States, residing at llo. 929,812, to F. B. Adamda'ted August One object of my invention is to provide a-panel boardsupport of the type described in said Adam patent above referred towhich is so constructed that the inwardly and outwardly adjustabledevice which car ries the panel board will also serve as a supportingmeans for the outside trim or finishing frame that surrounds the openingin which the panel board is set.

Another object is to provide a panel board support ofthe type referredto in which the adjustable device that supports the panel board isprovided witha part that snugly embraces the corner of-the panel boardlining and to whichsaid lining can be securely connected. I

Another object is to provide a panel board supporting means which is so'con structed'that the panel board can be adjusted inwardly'andoutwardly relatively to the wall or partition in which it is set, andalso adjusted vertically and horizontally so as to line it up or arrangeit in a perfectly straight position. And still another object of myinvention is to provide a panel board supporting device that comprisesfew parts and which can be adjusted easily.

()ther objects and desirable features of my invention will behereinafter pointed out.

Figure 1 of the drawings is a horizontal sectional view of a panel boardcabinet provided with panel board supports constructed in accordancewith my invention; Fig. 2 is a perspective view ,of one of my improvedsupports; Fig. 3 is a vertical sectional view taken on approximately theline 3-3 of 2; Fig. 4 is a horizontal sectional view taken onapproximately the line 4-4 of Fig. 3.

Referring to the drawings which'illustrate the preferred form of my,invention,

A designates a panel board cabinet of any preferred type arranged in anopening in a wall or partition 1, and 2 designates a panel boardarranged in a vertical position inside of said cabinet and provided witha lining 3 which projects outwardly so that its outer edge will bearagainst the inside face of the trim or finishing frame 4 which surroundsthe opening in the wall in which the cabinet A is set;

Supports 5 are arranged inside of the cabinet A at the fourcorners ofthe board, and each of said supports is provided with a device 6 towhich the panel board and the. lining are connected, said devices beingso constructed that they can -be adjusted -inwardly and outwardlyrelatively to the cabinet A and thus bring the outer edge ofthe lining 3flush with the outer face of the wall 1 in case the cabinet A is not setplumb with said wall. The supports 5 are also adjustablyconnected to thecabinet so that the panel board can be adjusted horizontally andvertically so as to line up the panel board or arrange it in a perfectlystraight position in case the cabinet A is set crooked. The means hereinshown for retaining the supports 5 in position consists of caps 7 whichbear upon flanges 5* at the inner ends of the supports and clamp saidflanges against the rear wall of the cabinet A, said caps being securedto the cabinet by means of screws 8 which pass through slots 5 in theflanges 5 of the supports. i

The adjustable device 6 on each support 5 is provided with a portion towhich the panel board is connected by means of screws 9 or othersuitable fastening devices, and also an angle-shaped portion 10 which embraces the corner of the panel board lining and extends approximatelythe entire depth ofsaid lining. The support 5 is substantiallyangle-shape in cross section so that the portion 10 of the adjustabledevice 6 will fit snugly inside of same, and said support 5 is providedwith an elongated slot 5 for receiving a bolt 11 or other suitablefastening device which is tapped into the angle-shaped part. 10 of thepanel board supporting device 6, a washer 12 being in- .terposed betweenthe head of said bolt and the support 5 so as to cause the device 6 tobe clamped tightly to the support when said bolt is tightened. Thesupport 5 is provided with flanges 5 that extend longitudinally of theslot 5, and the panel board supporting device 6 is provided with a guidelug 13 that lies between said side flanges and thus prevents the panelboard supporting device 6 from twisting or turning relatively to thesupport.

In the preferred form of my invention as herein shown, the clampingbolt-or screw 11 is tappedinto the lug 13 of the adjustable panel boardsupporting device 6 but it will, of course, be obvious that said screwcould be tapped into any other desired portion of said device.

Instead of connecting the outside trim or finishing frame 4 directly tothe support 5, as in the structure described in said prior Adam patent,I have provided the adjustable panel board supporting device 6 withmeans to which said outside trim or finish ing frame can be connected,said means preferably consisting of a lug 1 1 that pro jects laterallyfrom the upper end of the angle-shaped part 10 of the device 6. The lug14 is preferably arranged at the cornei of the angle-shaped portion .10and is provided with an opening 15 for receiving a fastening device 16which passes through the outside trim or finishing frame 4, but ifdesired, the portion 10 could be provided with a continuous flange or aplurality of lugs for securing the outside trim'thereto.

One of the desirable features of a panel board mounting of theconstruction above described is that it enables the part to which v thelining thereof to be adjusted horizontally and vertically so as to lineit up or arrange it in a perfectly'straight position in case the cabinetA is crooked; and still another desirable feature of such a structure isthat each support 5 is retained in position by means of a singlefastening device 8 which simply has to be loosened, but not removed,when it is desired to adjust the support to line up the panel-board.

The fact that the corners of the panelboard lining are snugly embracedby angleshaped parts 10 to which the lining is securely connected bymeans of screws 3* or other suitable fastening devices, overcomes Iclaim as new and desire to secure by Letters Patent is:

1. A panel board support comprising means which is adapted to beconnected to a stationary support, an adjustable panel board carrying,device mounted in said means and adapted to be adjusted so as to movethe panel board toward and away from said support, and means on saiddevice for carrying the outside trim or finishing frame that surroundsthe panel board open- 5a. A panel board supporting device comprising'amember which is adapted to be connected to a supporting structure so asto sustain a vertically disposed panel board in operative position, andan adjustable part on said member to which the panel board and.theoutside trim or finishing frame can be connected, said part beingadapted to be adjusted toward and away from the supporting structure towhich said member is connected.

A panel board supporting means com prising a member which projectslaterally from a supporting structure, a longitudinally adjustable parton said member to which the panel board is connected, and means on saidadjustable part to which the outside trim or finishing frame can beconnected,
